(Cl. 93-2) It is a further object of my invention to prol6 vide means of novel and improved design for mechanically wrapping a sheet of flexible transparent material about irregular objects or about suitable heads for the proposed package, and means whereby single sheets of transparent material may be utilized or suitable lengths may be cut as required from a roll of transparent material.

There are many other specific objects of the invention, relating to the provision of a support for articles of irregular contour during a wrapping operation, means for applying adhesive to a wrapper for the purposes of the practice of this invention, means for timing the admission to the machine of the sheet to be wrapped, means for rendering the device adjustable to handle varying diameters and lengths of packages, and other objects which will become apparent in the course of the following description.

1 and 2;

Figure '14 is a view in perspective of a package formed in accordance with the disclosure of Figure 13.

Like parts are identified by the same reference characters throughout the several views.

The machine frame designated generically at 15 may be mounted directly on the floor, as illustrated in Figs. 1 to 6, or may be mounted upon a suitable base 16, as illustrated in the form of the device shown in Figs. 7 to 11. In either case the frame 15 is provided with a means for supporting a supply of paper which in the first form of the machi e illustrated in Figs. 1' to 6 comprises a table 1'7 having guides 18 for a pile of sheets and in the second construction illustrated in Figs. '7 to 11 comprises trunnions 19 for a roll 20 of the paper to be used and suitable intermittently operable feeding and cutting mechanism for delivering automatically and at correctly timed intervals sheets of the proper size for the package to be wrapped.

The machine also includes a gluing device designated generically by reference character 21,

a paper registering and synchronized feeding device designated generically by reference character 22 and suitable axial and peripheral supports for the goods or package heads about which the paper is to be wrapped. All of these parts will now be described in detail, following which the operation of the device will be synchronized. The individual parts may be betterunderstood, however, if a preliminary statement of the principles involved is first given.

Principle of operation Fundamentally the invention contemplates the wrapping of a sheet of flexible material, such as 1 paper, about a pair of heads to the peripheries of which the paper is glued as it is wrapped so that upon completion of the operation a package or container results. In one form of the device the goods for which the package is intended are chine is adapted to suit these requirements by wrapping the transparent sheet directly upon the peripheries of the heads'therefor provided to construct a container into which goods may be introduced subsequently through a suitable opening provided in one of the heads of the container. The mechanisms used in performing these two separate operations are quite similar and the products are similar in that each comprises a pair of spaced heads supported from each other solely by a sheet of light weight highly flexible and highly transparent cellulose material through which the contents of the package or container are readily visible.

. The specific structureemployed for combining the various devices discussed above to make packages or containers in accordance with the aforesaid principles will now be described. Reference will be made first to the means for handling individual sheets and later the attachment for supplying such sheets from a continuous roll will be described.

Paper registering and synchronizing device The path of the paper can readily be followed by an examination of Figure 4. A sheet of paper removed from the stack upon table 18 is thrust beneath the continuously revoluble feed'roll 25 which rotates immediately above the surface of the paper and out of contact therewith. The guides 18 confine the paper laterally and the sheet is thrust forwardly until it contacts with a stop 26 which comprises a rectangular frame of wire shown both in Figures 4 and 5 and anchored rigidly to the link 27 for bodily vertical movement therewith. The transversely extending innermost side of the rectangular wire 26 is so formed up from the plane of the remainder of the rectangle (as shown in Fig. 4) as to form a sheet retaining s op.

Actuated by link 27 is a lever 28 pivoted at 29 and carrying a roller 36. When the link 27 is depressed by means of arm 31 the stop 26 moves downwardly with it out of the path of the sheet positioned against such stop by the operator and "simultaneously the roller 30 lifts such sheet slightly into engagement with the continuously revoluble feed roll, whereby such sheet is set in movement and advances into the bight between another feed roll 35 and a co-acting skeleton roll comprising a part of the gluing mechanism 21 now to be described.

Gluing mechanism The cross pin 36 of the frame carries straps 37 suitably spaced to support and guide the paper during its movement through the gluing mechanism. Paper released by the synchronizing stop 26 and fed by roll 25 is lifted by strap 37 onto the periphery of the gluing disks 38, best illus- =ltrated in Figs. 4 and 5. These disks are mounted .on shaft 39 which, through actuating connections hereinafter to be mentioned, is controlled by the operator for movement synchronously with the release and feeding of paper by device 22.

The disks are so adjusted upon shaft 39 as to register with the margins of the paper fed thereover. They are connected by a transverse strip 40 which appears in section in Fig. 4 and is cut away at 41 to clear the supporting straps37, as shown in Fig. 5.

The initial position of the parts is such that as the disks 21 and their connecting strip 40 are set in rotation such strip will precede the leading margin of the paper sheet advancing through the machine. The amount to which such strip leads the paper is so determined that the strip will contact the paper along its trailing margin to deliver glue thereto. In the setting of the machine illustrated, the adjustment is such that the machine will handle a sheet of paper only slightly less in length than the perimeter of disks 38. For a shorter sheet of paper the strip 40 will be set with a greater lead in advance of the surface of roll 44 it also is coated with ad-- hesive, the arrangement being such that the side margins and trailing margin of each successive sheet is rendered adhesive in traversing the gluing device 21.

Supports for materials during wrapping A tape 4'7 running over pulleys 48, 49, and 50 and bearing upon belt 55 throughout a large portion of the periphery of the wide roller 56 serves to hold the glued paper to the outer periphery of belt 55 and to ensure the delivery of such paper with the belt onto the upper surface thereof.

Belt 55 is provided with considerable slack and operates over the broad roller 56 and pulley 57. The slack or bight 58 in the belt not only supports the adhesive sheet of paper during the winding and gluing operation. but'also supports the carton heads 60 and the goods 61 to be wrapped. By way of illustration, Fig. 2 shows round cookies in position to be wrapped, but the machine is also capable of handling multisided and irregular articles such as square or hexagonal cookies or figs, small loaves of baked goods, fresh fruits, or any similar objects.

The carton heads 60 comprise shallow cups of paper or cardboard which are not rigidly positioned but ride in the bight 58 of belt 55 between axially yieldable head and tail-stocks 62 which are driven by belts 63 to rotate the heads 60 in approximate synchronism with the movement of belt 55. Springs such as that shown at 64 in Fig. 2 press the head and tail-stocks 62 ,toward each other from the supporting arms 65 in which the head and tail-stocks are adjustably carried from rod 66. I

The loose bight 58 of belt 55 cradles the heads 60 and maintains them and the goods 61 to be wrapped all in approximate axial alignment, or, if the goods are materially smaller than the heads, the belt will at least keep the goods within the projection of a cylinder between the approximately aligned heads.

With the parts in this position, the sheet of paper with adhesive side and trailing margins is fed upon belt 55 and passes beneath heads 60 and the goods 61 confined therebetween. The glued margins of the sheet 65' are pressed by the belt into peripheral contact with the heads 60 and adhere thereto. The length of the sheet is so chosen as to provide the desired degree of overlap between its ends after it has encircled heads 60 and the goods to be wrapped so that ultimately the leading edge of the sheet is overlapped by its trailing edge and the two edges adhere by virtue of the adhesive carried by the latter.

If required, a stationary guide of the form shown at 66' in Figs. 3, 4, 5, and 7 may be employed to overcome any tendency of centrifugal force to distend intermediate portions of the leading margin of the sheet as the sheet is woundonto the heads 60 and goods 61.

Actuating connections A motor 68 which may conveniently be suspended beneath the back side of table 17, as shown in Fig. 3, is beltedto a pulley 69 carrying a pinion 70 meshing with an idler transmission gear 71. Gear 71 meshes with a power distributing gear 72 mounted loosely on the shaft 39 by which the disks 21 of the gluing mechanism are supported. A clutch member '73 axially adjustable by means of the shifting lever 74 is splined to shaft 39 and adapted to clutch such shaft to gear 72 for rotation therewith. A spring 75 acting on connecting rod 76 normally maintains the clutch disengaged. It may be engaged, however, by manipulation of the mechanism best shown in Figs. 1 and 6.

A hand lever 77 controls the operation of the gluing disks by means of a roller 78 carried thereby and normally engaged in a notch 79 in the lever 80 to which connecting rod 76 is pivoted. The arrangement is such that when the lever 77 is manipulated it will oscillate lever 80," connecting rod 76 and lever 74 to engage clutch 73 with gear 72. It is contemplated that thelever should be immediately released to drop by gravity to its original position against stop 81. The clutch 73, however, will remain engaged because shaft 39 carries a drum 82 having a periphery notched at 83 to receive roller 84 carried by lever 80.

When the clutch 73 has been engaged by manual manipulation of lever 77 the consequent rotation of shaft 39 will bring .an unnotched portion of drum 82 beneath roller 84 thereby holding lever 80 in its outermost position against the tension of spring 75 to maintain the clutch in operative engagement. As soon as the shaft 39 has completed one rotation, however, roller 84 will drop into notch 83 thereby permitting the disengagement of the clutch and preventing shaft 39 from overrunning.

The device 22 for registering and synchronously feeding the paper sheet to be wrapped about drum 60 derives its movement from the clutch engaging operation of hand lever 77. The arm 31, already described as a part of the actuating connections of the gauge stop 26 and the lever 28 for starting the feeding operation, is supported by a rock shaft 85.which also carries arm 86 having an anti-friction roller 87 in the path of movement of lever 80. Thus whenever the lever 80 is shifted to engage clutch 73, rock shaft is simultaneously oscillated to drop the gauge stop 26 and to elevate roller 30 to press the paper into contact with the continuously revoluble feed roller 25, thus initiating the movement of the paper in timed sequence with the commencement of rotation of the gluing mechanism.

The paper feed rolls 25 and 35,9.re provided at one end of the frame with gears 89 and 90, respectively, with which the idler gear 91 intermeshes. Motion, is transmitted to this train directly from gear 72 with which gear is in mesh.

The shaft carrying pulley 48 also supports a pinion 93 which, through an idler 94, drives a gear 95 on the shaft 96 which supports the drum or broad pulley 56. From this pulley the subordinate pulley 57 supporting belt 55 is driven by means of sprocket 97, chain 98, and sprocket 99.

From the shaft 50 about which belt 47 operates, the belts 63 for driving the carton heads 60 receive their movement. The use of these belts is not essential but is found to be desirable when very slippery paper is used in the packaging operation. Shaft 50 may, if desired, be positively driven from the shaft carrying sprocket 99 and pulley 57 through the medium of sprocket 100 at the other end of such shaft, chain 101, sprocket 102, and pinion 103 (Figs. 1 and 2).

The gluing roll 44 carries a gear 105 meshing with the power distributing gear 72 and also with a pinion 106 which drives the squeeze roll 45. 100

The roll paper feeding and cutting attachment supported in journals 19. A nut 115threaded to 110 a bolt 116 serves to apply clamping pressure between the extremities of levers 111, whereby such levers are frictionally held to the pulley 113 so that roll 20 will not overrun during the dwell.

between successive intervals of feeding paper 115 therefrom.

The web 110 led from roll 20 passes through the bight of rolls 118 and 119, the latter being grooved at 120 to receive stripping fingers 121. Similar fingers at 122 are engaged in groove 123 in the feed roll 124, the fingers 121 and 122 being both supported by means of the transverse rod 125, as clearly shown in Figs. 8 and 10.

,- A like rod 126 supports another set of fingers 127 and 128, of which the former are also engaged in the grooves 123 of roll 124. The several sets of fingers and their associated supports comprise the upper guide members of a guide-' way caused by the plates 129 and 130. In the guideway thus formed between the supporting plates and the confining fingers, the web of pa.- per 110 traverses a closely restricted path.

Further intermittent advance of the web as required by the packaging machine motion is derived from shaft 39 of the packaging machine at such times as the latter is operated by means of the manually controlled clutch mechanism previously described. In order to take power from this shaft, it is, provided with a spiral gear at (Fig. 11) meshing with gear 136 which,. I

Approximately one-half of the periphery of disk 142 is relieved, as shown at 145 in Fig. 8. The disk element 143, however, is of the same radius as the unrelieved portion of disk 142. It is possible therefore to adjust the semi-disk 143 in such a way as to expose more or less of the relieved portion 145 of disk 142, as may be required.

The radiu of elements 142 and 143 is such that, except for t e relieved peripheral portion 145 of the former, these elements will jointly interact with roller 124 to feed the web 110 in a direction to advance it toward the packaging machine. Insofar as the relieved portion 145 of the combined disk is exposed to roll 124, however, the bite of the feeding device on the web is destroyed and the web is allowed to come to rest. The unrelieved periphery of the disk feeder therefore represents the proportionate period of advance of the paper during each rotation of shaft 140 and the relieved portion of the periphery represents a dwell in such advance. The dwell is desired for the operation of the cut off knife hereinafter to be described and the extent of the advance in proportion to the dwell will determine the length of paper which will be fed and thereby severed during each rotation of shaft 140.

At its outer end, shaft 140 carries a cam 147 for actuating the cut off mechanism. The nose 148 of this cam coacts with a cam foilower roller 149 mounted on a lever 150 and held to the periphery of the cam by a tension spring 151. The lever 150 -is fulcrumed at 152 and connected by a link 153 with a movable shear blade 155 pivoted to lie normally above the path of web movement and ad- J'ustable about an axis at 154 to sever the web in coaction with a relatively fixed shear bar 156.

The severed sheet extends from the shear bar between upper and lower guide fingers 157 and 158 carried by the attachment and upper and lower guide fingers 159 and 160 carried by the frame 15 of the packaging machine proper. The length of the space between the shears and the above described registering stop 26 of the packaging machine will preferably just correspond tothe required length of sheet and in order that this dis-.

tance may be adjusted to adapt the machine for handling any length of sheet which may be fed and severed by the attachment the entire attachment is mounted on a frame 161 which in effect comprises a carriage adjustable in a suitable guideway 162 on the base as indicated in Fig. '7.

The particular form of adjustable feeding device 141 will be found very advantageous for the purposes of the present invention, since the length of paper advanced to be severed by the machine is not dependent uptm any ratchet or other step by step movement in which the length of the severed blank will necessarily be a multiple of the unit of advance. On the contrary the present device is susceptible of infinite adjustment to feed a sheet of exactly the required length, within its capacity, and the distance.between the cut-off knife and the registering stop of the packaging machine is likewise susceptible of infinite adjustment, the fingers 157, 158, 159 and 160 being laterally ofl'set as shown in Fig. 10, to pass between each other without interference.

Operation A continuous web of paper 110 drawn from roll 20 against the resistance of friction arms 111 is passed between feed rolls, one of which is provided with a relieved peripheral portion of adjustable peripheral extent, whereby the web is intermittently advanced and is periodically permitted to come to rest for a period determined by the extent of the relieved portion. It will be obvious that the length of the web advanced between successive periods of dwell will depend upon the adjustment of the composite feeding roll and the extent to which an unrelieved portion thereof acts upon the web. A

During each period of dwell the length of web advanced during the preceding operation of the feed mechanism thereon is severed to provide a length of sheet corresponding to the adjustment of the feeding mechanism. The feeding mechanism is located at such a distance from the packaging machine that each severed sheet will lie immediately adjacent the registering stop of the packaging device in readiness for use in such device.

In the form of the packaging device disclosed in Figs. 1 to 6 of the drawings, the sheets for use therein are previously cut and are thrust by hand against the registering stop. In either case the action of the packaging device per se is the same.

. In packaging goods, the articles to be packaged are laid upon the bight 58 of belt 55 which, for sanitary purposes, may conveniently be made of some washable material such as rubber, although any form of belting will function satisfactorily from a mechanical standpoint.

-.The carton heads 60 will previously or simultaneously have been positioned between the head and tail-stock devices 62 to confine the goods to be packaged. As soon as the end members 60 and the goods 61 are in place on the moving belt 55, the operator will lift lever 77, thereby utilizing the connections already described to set the gluing disks 38 in motion and simultaneously to depress the registering stop 26 and to elevate the pressure disk 30 to feed the paper blank onto the gluing disk whereby its side margins and trailing margin are coated with narrow strips of adhesive.

The adhesively coated sheet passes rapidly about the outside of belt 55 and beneath the carton heads 60 and the goods 61 to be packaged. In passing beneath the carton heads the marginally adherent portions of the sheet will register therewith and will adhere thereto with the result that the sheet will wrap itself about the goods to be packaged and will bring its leading margin immediately beneath the overlapping and adhesively coated trailing margin whereby the packaging operation will be completed and the resulting package will comprise a product completely sealed by a peripherally extending sheet constituting the only means of connection between the two heads 60 to which such sheet is adhesively secured. 'If, as preferred, the said sheet comprises some highly transparent flexible, cellulose paper, the resulting package will be very attractive and will fully display its contents.

The one revolution clutch mechanism already described will stop the feeding mechanism and glue depositing feed roll after the single rotation required to complete the package. In the meantime, the attachment, or the operator, as the case may be, will have positioned a new sheet of material adjacent the registering stop of the packaging machine andwithin the potential bite of the feed mechanism of the packaging machine and it will only be necessary to remove the packaged article from the rotating belt 55 and to place thereon a further set of carton heads 60 with articles to be packaged confined therebetween. Thereupon the lever 77 will again be manipulated and the packaging operation repeated as often as may be required.

A slightly difie'rent operation is required in the -manufacture of an empty carton such as that shown in Figs. 13 and 14. In the operations already described, the sheet of peripherally disposed material is usually supported, at least in part, by the goods to be packaged, and the heads 60 are likewise supported to some degree by the, goods to be packaged. In order to make the carton where nmgoods are present, it may be found desirable to provide special cup-shaped head and tail-stocks 62, as shown in Fig. 13. In these the carton heads 60 and 60' are set and a belt 55 is used which is sufficiently narrow to fit between heads 62 and thereby to insure the pressure engagement of the sheet 65' with the carton heads.

Aside from these changes, the operation proceeds as above described and results in the virtually instantaneous wrapping of the sheet 65' about the carton heads with its margins adhesively joined to the carton heads and to each other to comprise a sealed package except for the opening 165 which is preferably provided in the carton head 60'.

Although it is not impossible to package small loose articles like candy by providing a deep bight 58 in belt 55, itis sometimes preferable to make up the cartons as shown in Figs. 13 and 14 for such articles and to seal opening 165 in the carton after introducing the candy therein. If transparent paper is used at 65, as above suggested, the resulting carton will be very attractive and will be as well adapted as a glass jar for the neat and full display of its contents. At 166 I have illustrated a square piece of transparent material applied over opening 165 to seal the carton shown in Fig. 14.
